 On the new EcoCFlex 3, one CNC controller for the machine and the integrated scara manipulator replaces the previously required PLC and robot control unit
 What strikes the observer first about the new EcoCFlex 3 is Dürr Ecoclean’s proprietary scara manipulator replacing the standard 6-axis jointed-arm robot, as well as the machine’s exceptional design. A view under the hood reveals further details contributing to its superior process reliability, quality, energy efficiency and availability rates in pre-cleaning and final cleaning of powertrain components.
In the pre- and final cleaning of powertrain parts such as cylinder heads, engine blocks and crankcases, robot cells not just improve flexibility. They also allow parts to be cleaned in short cycles, which makes them an indispensable asset in advanced engine and transmission manufacturing lines. With over 400 robot systems built, Dürr Ecoclean of Monschau possesses plenty of experience and has gained extensive customer feedback on optimisation potentials. Both went into the development of the new EcoCFlex 3 which is available in two sizes as a 3M and 3L version.
Custom-designed scara manipulator instead of a modified robotAn essential part of equipment is the robot, which is normally a modified standard type. However, despite extensive adaptations, these units cannot always cope with the harsh conditions encountered in cleaning applications, e.g., moisture, high temperatures and use of chemicals. As a result, unscheduled breakdowns and costly repairs occur time and again.
The EcoCFlex 3 does away with this problem. A scara manipulator developed by Dürr Ecoclean replaces the standard commercial 6-axis jointed-arm robot in this cleaning machine. Purpose-designed for use in a robot cell, this handling system is made entirely of high-strength aluminium and stainless steel. It needs neither paintwork nor a protective suit. Thanks to its IP69 protection rating, Dürr Ecoclean’s scara manipulator is resistant to high-pressure water jets and to immersion, in addition to withstanding booth temperatures up to 65°C. The cleaning chemicals employed may range from pH 6 to pH 10 and need no external robot manufacturer’s approval to be used or replaced.
